背景:胃癌患者的生活质量受到诸多因素影响,作者曾对此进行过分析,由于缺乏适当的统计学分析方法,因而未对这些因素影响生活质量的权重大小作进一步的研究。目的:提出一种综合指标的编制方法,分析生活质量诸因素的权重关系影响。设计:以诊断为依据的回顾性研究。地点和对象:1998/1999年期间经省级医院确诊的胃癌患者396例,均由福建省肿瘤防治办公室提供,年龄32～75岁。方法:对396例胃癌患者用自行编制的调查表进行生活质量及相关因素的调查。主要观察指标:对每个胃癌患者的18个反映生活质量的条目作评分,计算每个胃癌患者的这18个条目的总分作为观测变量。结果:从影响生活质量总分的8个变量中得到3个综合变量,对胃癌患者生活质量的影响权重分别为:0.35,0.32,0.33。结论:采用该方法进行胃癌患者生活质量的影响因素分析,可以得到各影响因素综合变量对生活质量的影响权重;胃癌患者的社会经济状况及康复锻炼对其生活质量有较大的影响。 BACKGROUND: The quality of life of patients with gastric cancer is influenced by many factors that the authors have analyzed and, in the absence of adequate statistical analysis, does not further study the weight of these factors that affect the quality of life. OBJECTIVE: To put forward a method of compiling comprehensive indexes and analyze the influence of the weight relationship among the factors of quality of life. Design: A retrospective study based on diagnosis. Location and Subjects: 396 cases of gastric cancer diagnosed by provincial hospitals during 1998/1999 were provided by Fujian Provincial Office of Cancer Prevention and Treatment, aged 32-75 years. Methods: 396 cases of gastric cancer patients with self-compiled questionnaire for quality of life and related factors in the survey. MAIN OUTCOME MEASURES: Eighteen entries reflecting the quality of life of each patient with gastric cancer were scored and the total score of these 18 items for each patient with gastric cancer was calculated as an observation variable. Results: Three comprehensive variables were obtained from the eight variables that affect the total quality of life score, and the weight of the influence on the quality of life of gastric cancer patients were 0.35,0.32,0.33 respectively. Conclusion: This method can be used to analyze the influencing factors of quality of life of patients with gastric cancer. The comprehensive variables of influencing factors can get the weight of quality of life. The socio-economic status of patients with gastric cancer and rehabilitation exercise have a greater impact on their quality of life.
